[SSG] new version of R (2.14, linked against Intel MKL)

Print Friendly, PDF & Email

We have installed a new version of R - 2.14.0 to be precise, linked against the Intel Math Kernel Library (MKL). In our tests, this version greatly improves matrix operations when compared against the standard GCC-compiled R. The standard R-benchmark-25.R ran about 4 times faster. R-2.14 is installed on all SSG and SDS nodes, and is the new default R. If you wish to run the older R 2.13, you can call it with ... R-2.13. Please let us know if you run into any problems.
